Title: Improvements in apparatus for comparing the intensities of light beams
Inventor: D OMBRAIN GEORGE LEE
IPC: G01J1/16
Filed: 1951-11-12
Abstract: 727,474. Photo-electric trigger switches. PERMUTIT CO., Ltd. Dec. 23, 1952 [Nov. 12, 1951], No. 26453/51. Class 40 (3). Apparatus for triggering an indicator when the intensity of two light beams differ by a predetermined amount comprises two photo-cells, energized by the respective beams, connected in opposition to produce an unbalance current through a mirror galvanometer, whereby at a given deflection the galvanometer movement is augmented by the output of a further photocell energized by a beam reflected by the mirror of the galvanometer, the increased unbalance current causing operation of a relay to close an indicator circuit. As shown, Figs. 1, 2, applied to the measurement of the turbidity of a test solution, to supply a warning when the turbidity equals a certain value, light from a lamp 38 passes through a standard cell 30 and text cell 32 to reach photo-cells 40, 42 respectively connected in opposition across a mirror galvanometer 50. At a predetermined turbidity in cell 32 the difference in output from the photocells 40, 42 produces a deflection of the mirror 52 to direct a further beam from the lamp 38 onto a photo-cell 58, whereupon positive feedback occurs and the galvanometer deflection continues to increase until checked by a stop 64, with the beam fully on photo-cell 58, whose output is now sufficient to operate a relay 66 and close a warning circuit at 68. The effect of stray light on photo-cell 58 is neutralized by a photo-cell 60 connected in parallel opposition with photocell 58. In an alternative arrangement the outputs of photo-cells 40, 42 are fed to the grids of two triode valves whose anode currents are fed through two opposing windings of a mirror galvanometer and also through two opposing windings of a double-winding relay, to energize it when the difference in photo-cell outputs causes a predetermined difference in anode currents. In modifications the positive feedback may be produced by diminishing the output due to the less-intense beam, and the mirror may be replaced by a moving vane to produce the instability at a given unbalance.

Title: Improvements in or relating to communication systems employing code modulation
Inventor: BOND ROBERT FRANK
IPC: H03M3/02
Filed: 1966-06-14
Abstract: 1,133,672. Selective signalling. GENERAL ELECTRIC CO. Ltd. 13 June, 1967 [14 June, 1966], No. 26555/66. Addition to 1,085,843. Heading G4H. The #-# modulation system of Specification 1,085,843, is modified in that the amplitude of the pulses of the feedback signal added to the input signal in an adder 5 are raised in accordance with the number of pulses in the encoded signal in at least two closely preceding pulse positions. In the embodiment described, the outputs of first and second triggers 12, 15 the states of which represent the signals transmitted in the two preceding pulse positions are compared in a logic circuit 16 which supplies one of two voltage signals to a transistorized clamping voltage generator 17 depending on whether either two or no pulses are transmitted or whether only one pulse was transmitted. The voltage generator 17 feeds two voltages of equal magnitude and opposite polarity to a clamping circuit 19, the magnitudes of the voltages tending towards a minimum when only one pulse was transmitted and tending towards a maximum when two or no pulses were transmitted. The inverse pulse signal from trigger 12 is also fed to the clamping circuit 19 so that the pulse signal fed to the adding circuit 5 is the inverse of the encoded signal but the amplitude of the pulses varies with the magnitude of the outputs of the clamping voltage generator 17. The encoded signal amplitude modulates a radio frequency carrier wave and is transmitted to a receiver where it is decoded back to analogue form.
